INSECT GUARD Filed Jan. 14, 1933 1 k INVENTOR 1 u BY Q ATTORNEY l Patented Feb. 27, 1934 UNITED STATES PATENT OFFICE Application January 14,

Claims.

The invention relates to insect guards and more particularly to guards applicable to conventional sliding double sash windows.

Where half length window screens are used a 5 space always exists between the top part of the lower sash and the window pane of the upper sash. The principal object of the present invention is to provide a guard to cover this space and thus prevent insects from entering the room.

The guard is of an extremely simple nature, thus making for economy of manufacture and ease of installation.

Other objects and advantages will become apparent as the specification proceeds.

Referring to the drawing forming a part thereof and in which preferred embodiments of the invention are illustrated Fig. 1 is a plan view, the device being shown in an extended position by the broken lines;

Fig. 2 is an edge view;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is an end view; and

Fig. 5 is a detail elevational view showing a form applicable to wide windows or windows having more than one pane therein.

Referring again to said drawing and more particularly to Figs. 1 to 4, the device comprises a shield, preferably of metal, constructed of two units 10 and 11 which are suitably joined together in sliding relation to each other.

The unit 10 has two or more mushroom-shaped guides 12 struck up from it and these guides cooperate with channels or slots 13 formed in the unit 11. The units are thus joined together so they can slide to and fro in a straight line thus compensating for different widths of windows. While a preferred form of securing the units together in sliding relation to each other is illusw trated and described it is to be understood other known means might be utilized.

Means are provided for securing the shield to the top part of the lower half of a double sash window so as to cover the open space formed between the two half windows when a wire screen is set under the lower sash. This means comprises T-shaped brackets 14 having holes 15 in their lower legs for fastening means such as screws. Mounted in the upright parts of the T-shaped brackets are trunnions 16 to which are secured the units 10 and 11. In this manner the shield may be swung toward or away from the window pane in tho upper sash when desired.

In connection with the brackets 14 means are also provided to prevent vibration and rattling of 1933. Serial No. 651,743

the shield against the window pane. For this purpose the upper ends 17 of the upright parts of the T-shaped brackets have threaded apertures for thumb screws 18. These thumb screws can be so adjusted as to contact with the side members of the upper sash so as to prevent vibration and rattling of the shield against the window pane.

Fig. 5 illustrates a form applicable to extra wide windows or windows having a number of panes or sections. If the form illustrated in Fig. 1 Were disjointed the guides 12 of the unit 10 would cooperate with the slots 20 in the left hand part of Fig. 5 and the slots 13 in the unit 11 would cooperate with the guides 21 in the right hand part of Fig. 5. To lend greater stability, a hinge 22 is provided between the units shown in Fig. 5 and this hinge may be secured to the sash in any convenient manner. The number of units may be multiplied as often as desired in accordance with the foregoing plan and thus accommodate windows of various widths.

Such changes in details of construction and arrangement of parts as might occur to one skilled in the art are to be considered as coming within the spirit of the invention and the scope of the appended claims.

I claim:

1. A metal shield constructed of two separate units with two mushroom-shaped guides in one unit and two channels in the second unit, said units joined together by said guides and channels to slide to and fro in a straight line, said shield being attachable to the top of a lower half of a double sash window to cover the open space formed between the two half-windows when a wire screen is set thereunder.

2. A metal shield constructed in two separate units with two mushroom shaped guides in one unit and two channels in the second unit, said units joined together by said guides and channels to slide to and fro in a straight line, said shield being attachable to the top of a lower half of a double sash window and set to fit the frame molding and cover the open space formed between the two half-windows when a wire screen is set thereunder.

3. A metal shield constructed in two separate units with two mushroom-shaped guides in one unit and two channels in the second unit, said units joined together by said guides and channels to slide to and fro in a straight line, said shield being attachable to a top of the lower half of a double sash window, and set close against the glass panes of the upper half-window, and which ward out of the path of said cross moulding and forward to fit against the window glass panes.

5. A metal shield constructed for a double sash window in two separate units with two mushroomshaped guides in one unit and two channels in the second unit, each unit connected to a bearing having a tube-top tapped for a thumb screw to fit therein for the purpose of screwing against the upper sash of the window to prevent vibrating and rattling.
